Credit for figuring these out/discovering them goes to Perry. I find myself referring to them in a training binder I got from last year’s NY Training Summit and figured it would be easier to just get them up on the web so I don’t have to go hunting for that binder every time. The following code works for Classic.

Subform Considerations

Subforms have to be handled differently than forms when it comes to JavaScript because while in the form designer, the two things look identical, the way that myEvolv renders a subform in the browser is very different from how it renders a form. But it isn’t radically different and the main changes account for the fact that a subform can have one or more rows and so you need to be more specific about which field you are trying to manipulate so that you don’t change every line simultaneously.

Scenario 1: Get the Value of a Subform Field

This code is for use within the subform, e.g. if you want to default the value of one field based on the value of another on the same subform.

self.getElementFromXML(currentRowXML, 'column_name');

Note the self object is being used here. This is the subform object as distinguished from the parent form object. The parameter currentRowXML then further narrows it down to the current record/row on the subform that you are concerned with.

Scenario 2: Set the Value of a Subform Field

Again, for use within a subform, this code can be used to set the value of a field in the same subform, e.g. when you want the On Change event to auto-populate a field.

this.form.'column_name'.value;

If you are checking a checkbox, use this code:

this.form.'column_name'.checked = true;

Note that in this code, you do keep the single quotes in the code for it to work properly. All you change is the column_name

Scenario 3: Get the Value of a Parent Form Field

With this code, you can get the value of a field in the parent form based on an action in the subform.

window.parent.getFormElement('column_name');

Note the window.parent is the only difference from the code you would use on the parent form. This is what allows your code to ‘jump up out of the subform’.

Scenario 4: Set the Value of a Parent Form Field

Maybe you figured it out by now but you can use the same small change to set values on the parent form from the subform.

window.parent.setFormElement('column_name', value);

Scenario 5: Trigger an Alert from the Subform

Alerts are useful in guiding user activity and you can trigger them from subforms. Similar to the last two, the trick is moving back up the DOM to the parent form to trigger it.

window.parent.window.alert('Alert Message');

Other Possibilities

It is possible to go the other way and get and set values on subform records from the parent form, however, it becomes a much more complex problem that requires very specific solutions for very specific challenges. That is because of the One-to-Many relationship that the subforms have with the parent form. For these types of situations, you will probably be targeting the subform itself and then looping through each record to get or set values.

There are times when it is useful to analyze the Document Object Model of your myEvolv form, especially when you are trying to figure out ways of manipulating the form with JavaScript. If you are on a main screen in myEvolv, you can simply press the F12 key on your keyboard to bring up Internet Explorer’s developer tools. However, this does not work when you press it while focused on a modal pop-up in myEvolv.

In order to get the developer tools to work so that you can see the DOM for your event forms, follow the steps below.

1) Disable Setting that Allows Websites to Suppress Address Bar

Open Internet Explorer’s Internet Options and click on the “Security” tab. Make sure “Trusted Sites” is highlighted and click the “Custom level…” button.

In the Security Settings dialog, scroll down to the Miscellaneous settings. Select “Disable” for the setting “Allow websites to open windows without address or status bars”. Apply the settings and close the Internet Options dialog.

This setting will cause the modal popups that myEvolv uses to display event forms to display their url, which is required for developer tools to be used on a window.

2) Open Developer Tools and Un-Pin it From the Browser Window

At this point, some of you may be able to simply open an event form in myEvolv and press F12 and the developer tools open without problem. For others, nothing happens when F12 is pressed in a modal or you get a warning that says the main windows developer tools will need to close so that i can open a new one in the modal but then nothing happens.. The rest of the steps in this post will show the workaround for that.

The first thing you will need to do is un-pin the developer tools from the browser window so that they open in their own separate window. Close any modals you have open and press F12 so that the developer tools open in the browser. In the upper right hand corner of the development tools pane, there is an un-pin button you can click. The develop tools will then open in their own separate window.

3) Open The Event and Select the Right Form in the Debugger

With the Developer tools in their own window, you can open the event that you want to analyze with developer tools and still have access to the developer tools window. When you open the event, it will not automatically populate in the developer tools. You must select it in the “Debugger” tab.

Click the Debugger tab and note that the pane below the toolbar support multiple tabs. You will probably see main.aspx loaded in the pain and that represents the main screen of myEvolv. At the bottom of that pane is a debugger pane. Find an error or warning related to eventform.asp. It should be shown as a link and clicking that link will load the event_form DOM in the debugging pain next to main.aspx.

UPDATE: Easier Way

Instead of going through the last steps 2 & 3 above, you can just copy and paste the url for the modal into a new tab in Internet Explorer and then launch developer tools for that tab.

Some payors are beginning to require that client addresses utilize the ZIP+4 ZIP code in order to get paid. The ZIP code field in myEvolv has a datatype of Zip Code which appears to be a string field that allows up to 10 characters. This means that you can store a 5-digit ZIP code or a ZIP+4 in the field. Furthermore, the functionality for auto-filling the city and state fields based on the ZIP code will work with either type of ZIP code.

One thing that is lacking is the ability to force users to input a ZIP+4 in the ZIP code field. The following guide will show how you can add some form validation to the Client Demographics form that will help to prevent users from entering only the 5-digit ZIP code. While we will be looking at only one set of forms, you should be able to apply the same changes to other forms and address subforms to achieve the desired result elsewhere in the system that addresses are collected or edited.

Setup New Demographics Formset Member

For the purposes of this demo, we are going to modify the Client Demographics form.
This is a system form and we cannot directly make changes to it so instead, we must create a custom demographics form, address subform and formset member so that we can make the changes we want.

Copy the ‘Address by ZIP code‘ Form

This form is in the Address Info for People form family. This is the form that is used for the Personal Address subform on the Client Demographics.

Copy the ‘Client Personal Information‘ Form

This form is in the Personal Information form family and is listed at the top as the default form. This is the main form that loads when you go to the Client Demographics formset.

On your newly-copied, custom version of this form, swap your custom Address by ZIP code subform in for the default Address by ZIP code subform.

Remember that when you copy and begin editing these system forms, a good rule of thumb is to only add to the form or carefully edit what is on the form so that you do not have downstream effects. Avoid deleting elements. If you don’t want them to be visible, simply hide them.

Create New Formset Member

Select the Client Personal Information FormSet in Formset Maintenance. By Default, the Client Demographics formset member is ordered #1. Add a new formset member and copy the settings for it just like the system default Demographics formset member EXCEPT that we will be using our custom Client Personal Information form instead of the system form in the Default Form field.

With the new formset created, remember to make it available to all navigation schemes which need the ZIP+4 validation. In order to avoid confusion, you can make the default formset member unavailable to those with the new formset.

Pro Tip: I temporarily put “TEST” in the Tab Caption of my custom formset so that I could find it easily when adding it to the navigation schemes.

You now have a separate and customizable Client Demographics formset to play with in your system

Modify Forms to Validate for ZIP+4

We will need to make changes to both of our forms in order to cover all of our bases. Our method for validating is to check the subform zipcode field when it is changed and determine if the zipcode entered is comprised of 10 characters. If the zip code is other than 10 characters, we will alert the user that they must enter a ZIP+4. If they ignore the warning and attempt to save anyway, we will prevent the save and alert them again that a ZIP+4 must be entered.

Custom ‘Client Personal Information’ Form

Step 1) Add a variable to the form just above the Personal Address subform. This variable will be used to store our ZIP code validation state that we will check before saving.
I named my variable is_zip_invalid and gave it a Regular Numeric datatype. You can set your variable to be not visible.

Step 2) Add the following code to the form’s “Before Save Code” property:

The code above checks to see if the value of the variable we just created is ‘1’. If it is, then it gives an alert and tells myEvolv to abort the save because this form is not valid. On the subform, we will add code that will set the value this variable based on what is entered in the zip code fields.

Custom ‘Address by ZIP Code’ Form

Step 1) Add the following code to the ZIP Code field’s “On Change” property:
This code can go under the setAddressFromZip(this); line.

The code above creates a variable named zip and assigns it the value that user enters into the ZIP Code field. The script then checks to see if the value is 10 characters long. If it is not, the code produces an alert to remind the user that a ZIP+4 is required and then sets the value of is_zip_invalid on the parent form to 1. If the value is 10 characters long, the script sets the value of is_zip_invalid on the parent form to 0.

Step 2) Add the following code to the form’s “Before Save Code” property:
Since it is possible for users to open the subform in a new window, we also need to do some validation on the subform itself in case a user ends up adding or editing addresses via this method/

var zip = getFormElement('zip_code');if(zip.length != 10){{alert('You must enter a ZIP+4 in order to save');formValid = false;}}

The above code does the the same thing that the “Before Save Code” from the other form does. The only difference here is that we have direct access to the value entered in the ZIP code field so we use that to validate the form rather than the variable flag.

When put altogether, you will have a custom Client Demographics formset that will warn users at the time of changing a ZIP code field if they are not entering a ZIP+4 and will not allow saving until the ZIP code is fixed.

One Vulnerability

The way that this is setup, the value of our variable is_zip_invalid is changed any time a zip code is updated so if the last zip code altered is valid, all zip codes will be accepted as valid. So for example, let’s say that I edit two zip codes on the form. On the first one, I only put in the 5-digit ZIP code. I get an alert telling me to use the ZIP+4 and my variable gets assigned a value of ‘1’. Next, I close the alert and alter the second ZIP code and this time I enter the ZIP+4. Our code executes to check that the ZIP code I entered here is valid. It sees that it is and assigns our variable a value of ‘0’. The form will successfully save even though I still have a 5-digit zip in the first address that I edited.

More complicated code might be able to do a more thorough job of validating multiple zip codes before save but I haven’t figured that out yet.

When working on treatment plans in myEvolv, you will notice that many of the treatment plan component forms contain both a start date and a target completion date. One of the programs I was building a treatment plan for wanted to have the target completion date on the form but always wanted it to be 90 days from the start date. Instead of making each clinician calculate 90 days from the start date and fill it in themselves, I used this method to take the date value from the start date and update the target completion date field with a value that is 90 days later. I will walk you through the JavaScript that I used so that you can make adjustments based on your needs. The full snippet of JavaScript will be at the end.

Where does the code go?

The first consideration is where to put the JavaScript. In this case, used the ‘On Change Script’ field property on the field that will be modified by the clinician, ‘start_date’. myEvolv provides us with access to 3 events that we can use to trigger our JavaScript handlers (the code we want to execute): ‘On Change’, ‘On Click’ and ‘On Load’. The ‘On Change’ event is fired when the value of the field has been changed. This is the most suitable event to use in this situation since I do not want the new date value to calculate until there is a value in the first date field. Furthermore, if a clinician makes a mistake entering the start date, I want the new date to recalculate when the clinician makes an adjustment. Both of these scenarios are covered when using the ‘On Change’ event.

Get the ‘start_date’

The first line of JavaScript code’s purpose is to get the value that has been placed into the ‘start_date’ field and convert it into a proper JavaScript Date object so that we can manipulate the date easily. I declared a variable named date and set it to be a new Date object passing the value of the ‘start_date’ field as its argument:

var date = new Date(getFormElement('start_date'));

Calculate the ‘target_date’

Now with the date entered by the clinician converted to a Date object, I can perform some calculations on the date using the ‘getter’ and ‘setter’ methods built in to JavaScript Date objects. In my scenario, I need the ‘target_date’ field to be +90 days from the ‘start_date’ so I used the getDate() and setDate() methods:

date.setDate(date.getDate() + 90);

If I wanted to do +3 months instead, I would use the getMonth() and setMonth() methods:

date.setMonth(date.getMonth() + 3);

If I wanted to do +1 year, I would use the getFullYear() and setFullYear() methods:

date.setFullYear(date.getFullYear() + 1);

There are also methods for getting and setting hours, minutes, seconds, and milliseconds, but I am dealing with Date Only fields in this scenario.

Format the ‘target_date’

Now that the date object has my new date stored in it, I need to put that value into the ‘target_date’ field. However, the date in the date object is not formatted in a way that myEvolv’s date fields like so I need to pull the individual date elements from the object and build a string value to place in the date field. I accomplish this first by declaring variables for the month, day and year:

Now I declare a new variable called formatted_date and set its value to a concatenated myEvolv-friendly string:

var formatted_date = mm + '/' + dd + '/' + yyyy;

Set the ‘target_date’

setFormElement(‘target_date’, formatted_date);

One Caveat

You may be inclined to disable the ‘target_date’ form field so that clinicians cannot change the value after it has been calculated. I was unable to get that to work, however. When a form field is disabled, it is excluded from being saved so for now it would seem that you have to keep the form field modifiable. If you used this same similar* code in the ‘On Change Script’ property for ‘target_date’, you could prevent the ‘target_date’ from being changed by effectively reverting any attempts at changing the ‘target_date’ manually.

*You will need to also add some JavaScript to validate that the ‘target_date’ has been changed because if you just put this exact same code in the ‘On Change Script’ property for ‘target_date’, you will end up in an infinite loop when ‘actual_date’ is changed on the form and you will crash the browser.

I have found that it is often small things that can make all the difference in how user-friendly our myEvolv processes are. One problem that we ran into with myEvolv was that if you were in the middle of working with a form where you needed to select, say, a collateral but that collateral had not yet been added for the client, you would need to save the form as a draft (if allowed), navigate to the collaterals formset member to add one and then return to the original form to select the collateral. If you have experienced this, then you know how annoying it can be.

My solution to this issue was to add urls to our forms that would launch the collaterals wizard without the need to close the form at all. Users are then able to add collaterals on the fly. This could be used for other relationships like health providers or families and possibly even things outside of the relationships formset. This post will demonstrate how to create a URL form variable to launch the collaterals wizard but you should be able to apply the same steps to other formset members and achieve the same results.

Adjust Your Browser Settings

myEvolv creates popup windows just like any other website by opening a new browser window with it’s own URL. The default browser settings for Internet Explorer allow myEvolv to hide the URL of those popups but we want to examine the URL because we want create our own URL’s to display on our forms that will open the same windows. To make the URL visible on popups:

1) In Internet Explorer, go to Internet Options
2) Click on the “Security” tab
3) Make sure you are in the “Trusted Sites” zone and click “Custom level…”
4) In the “Miscellaneous” section of the “Security Settings”, DISABLE “Allow websites to open windows without address or status bars”
5) Click “OK” and then close Internet Explorer Settings

With this setting disabled, you will now see the URL for all popups that myEvolv creates. See the image below for the before (top) and after (bottom).

What’s in a myEvolv URL?

I am interested in getting the URL for the popup window that is created when I go to create a New Manual Event for a Personal Collateral so I pick any client and open the form to add a new personal collateral. The URL for that window is long so let’s break it down and see what we can determine about it. Below, I have the URL and have added a line break before each &

We want to keep this URL the same as much as we can but there are some variables we need to identify in here so that we can generate a unique URL for each form instance based on whose client record we are working on. If I just dumped this URL onto a form statically, I would always be creating collaterals for the client whose record I had open when I grabbed this URL along with some other problems. The parts we need to examine more closely are anything with a GUID.

The pieces of this URL that we will need to generate dynamically on our form are

parentValue – this is the people_id of the client for whom we would be creating the collateral

sessionID – this is the id of your current session. If this is not updated for each login session, the popup window will take you to a myEvolv login screen

serviceTrack – this is a client-related id similar to the parentValue

event_id does not need to be changed. I am not sure what it is but the value stays the same no matter which client record so its safe to bet you can keep it static.

Form Design – Adding a URL Variable

On your form, insert a new variable wherever you want it to display on your form. You can name the variable whatever you would like and caption it however you would like. I typically make the field not modifiable so that users can’t make changes to the url that might have an adverse effect. You might also want to shorten the display length so that it looks better on the form.

We then need to concentrate on generating the URL string that will be our default value for this variable. For those of you who have not done URL string building, it just involves a lot of string concatenation. We first create a variable and assign it a string value that is equal to the first chunk of static text. Then we concatenate our first variable. Then concatenate the next chunk of string that is static and so on until we have our full url.

The first section of the url that is completely static is https://myagency.netsmartcloud.com/new_person_form.asp?process_code=COLLATERAL&form_id=NEW_COLLAT_SEARCH&parentValue= so the first line of our code will be

Then we need to append our variable for parentValue, which is the people_id of the client whose record we are in. That comes to the current form already loaded in a variable called parentValue so we can just plug that in here

Troubleshooting Tip

You can see the results of your concatenation in the URL variable on the form so if you keep it modifiable and give yourself a generous display size, you can check to see where you might have left pieces out by mistake.

Quirky Behavior

If you built your URL string correctly, you should launch the Add Collateral window from your form. One thing I have noticed is that after you fill out the form and hit save, the form does not close or give any indication that the collateral had been added successfully. One challenge in getting the form to behave any different is that these forms are system not-modifiable so we don’t have the ability to go in and add a window.closeAfterSave = true snippet to them. Users must be trained to close the window manually after they have saved the form without triggering an error for things like blank required fields.

This post comes from a reader request. The scenario she was facing is that when a referral is created in myEvolv, you must enter a referral source and a referral reason on the form. When you go to perform an intake from the referrals, this information is not pulled into the client record. She wanted to have the Referral Source and Referral Reason fields on the client initial enrollment AND also have those fields pre-populate with the options that were selected on the referral.

Intake Form Setup

The Initial Enrollment from Accepted Referral form is in the Agency Intake form family. Agency intake events are not user modifiable so we have to modify the system form to add the fields for Referral Source and Referral Reason.

Referral forms use the refrerrals_to_agency table and the intake forms use the service_track table, so we will need to add new database fields to the intake form to hold our Referral Source and Referral Reason values. We will set them up just as they are on the referral form, using the same picklist and and dependencies.

Referral Reason

We add a new database field called udf_referral_reason and give it the following attributes:Data Type: Foreign Key IDForeign Key Column:referral_reason: referral_reason_idLook-up Table Used: Referral Reason Table

Default Values

At this point, the intake form has a place to store the referral source and referral reason but the user would have to manually re-select those values, which is a pain and also error-prone. We know the information is in the referrals_to_agency table, so we can use the getDataValue() form function to obtain the data but how do we know which row to select.

When you perform a client intake from accepted referral, the intake event “belongs to” the referral made event. The referral made events are the subform entries for Program Recommendations on the Referral form. In turn, those referrals made events “belong to” the referral form that houses the referral source and referral reason data we need. Once you have selected the accepted referral from which you are completing the intake, myEvolv sends a belongs2Event parameter to the intake form so that when the intake is saved, the intake is linked to the parent referral made. That value is equal to the event_log_id of the referral made event, which means we can plug it into the getDataValue() form function to get the value that referral made event’s parent event_log_id and then use that value to return the referral source and referral reason values.

Explanation of Code

First we use the belongs2Event value that is passed to the intake form from the referral made event so that myEvolv can properly link the two events in the tables. We use that value to get the event_log_id of the referral made event’s parent event which is the referral event using the form function getDataValue()

We then use referral event’s event_log_id to get the value of the referral source and referral reason fields on that referral event again using getDataValue()

Conclusion

With this setup in place, when you perform an intake from accepted referral, the referral reason and referral source from the related referral should be on our intake form. Note that this setup enters duplicate data to what is on the referrals_to_agency table into your service_track_x table. If we wish to avoid saving duplicate data to the database, we can setup the new fields on the Intake form as variables instead. This will allow us to display the referral source and referral reason on the intake form when it is opened in myEvolv but no data from the variables will be saved to tables when the intake is saved.

EDIT 8/3/2018: Reader Rosemary asked about using text templates in conjunction with this code rather than including the raw HTML in the JavaScript code. Indeed there is a way to do that, so I have included that method at the bottom of the post. Reviewing the post also exposed that my code had a syntax error so I fixed that. Thank you, Rosemary!

Progress notes in Evolv are system fields in myEvolv that have special properties that make them particularly useful in certain situations. For example, the Progress note field is included in many of the views available to subreports so being able to use the progress note column on a form allows the data contained therein to be fed back on other forms via subreport.

Unlike other form fields, however, you do not add a progress_note field to your form in the form designer. Instead, you add the progress note in the Event Setup area by checking the “Has Single Note” checkbox.

Just like with the Service Related Encounter Information that I addressed in another post, checking this checkbox will append fields to your form at the time that the event is launched. Unlike the Service Related Encounter Information, however, there is no way to add the progress note field to your form in the form designer so that you can manipulate its attributes. It is therefore tricky to set a default value for the progress note, but not impossible. The following guide will show how you can use jQuery and the form header attributes to simulate the use of the default value attribute on a progress note field. This can be useful for defaulting in a template when you know only one template would be used and you want decrease the risk that the clinician forgets to apply the template.

How Memo Fields Render

One of the things that makes manipulating a Memo field more difficult in myEvolv is that they are a much more complex field being rendered on the form. With a custom_string type of field, for example, there is just a label/caption and an html input field so you can use some pretty basic javascript to get and set the value of the field or use some of the formfunctions.js functions to get or set the form elements.

Memo fields, on the other hand, have their own menus for manipulating the formatting of the text and spellcheckers, etc. When you are dealing with a Memo field, you are actually dealing with an iframe element that contains a series of div elements that hold those buttons and then finally, buried deep in the iframe you will find a div with the id of “Composition”. That is where the text value of the memo resides.

Further complicating things is the fact that unlike other types of fields that you can easily target by column name, Memo fields must be targeted by their id, which is the GUID that represents their form_lines_id.

Accessing the Text Value of a Memo Field

To target the divelement that contains the text value of your memo field, you must turn to jQuery and use the following code:

Since the Progress Note field is a system column that has existed for a long time, it has the same form_lines_id in everyone’s system, so to get the memo text of a Progress Note memo field, plug in the form_lines_id:

Explanation of Code

var memo_text =
This creates a variable called “memo_text” that will hold the value of the memo field we target.

$('#BFE6BE66-7983-4C3B-8374-1606E7D909A5')
This targets the element on the form that has and id of ‘BFE6BE66-7983-4C3B-8374-1606E7D909A5’, which is the progress note’s iframe. If you want to target a different memo field, you will need to determine the form_lines_id of that field and plug it in here.

.contents()
This gets all of the contents of the iframe targeted above.

.find('#Composition')
This searches the contents above for an element with an id of “Composition”. This is the element that contains the Memo field’s text.

.html()
This gets the html value contained inside the “Composition” div targeted above. We use the html() method because this will preserve the rich text formatting that has been applied to the text in the box.

Setting the Value of the Progress Note

You can set the value of the progress note field with very little changes to the above code. if I want to set the text inside the progress note to “Hello”, I use this code:

Since we are using the html() method, you can insert HTML markup with your text, which is what will allow you to insert a nice template. Remember that you have to escape your >’s and <‘s

Replicating the Default Behavior

Using the code above, we are able to manipulate the text inside the Memo field with On Change and On Click events on the loaded form just fine, but what can we do if we want to default a specific value into the progress note field when the form loads?

We can use the code above to set the value but we need that code to fire AFTER the form has been loaded. Fortunately, there is an attribute on the form called After Load Code that we can use as the trigger for this code.

But, it’s not as simple as just dropping the code in there because while the code in this field will fire after the form loads, it does not necessarily fire after the memo field iframes are loaded. it is therefore necessary to wrap the code in a javascript setTimeout() function.

The setTimeout() function takes two arguments. The first is the code that you want to execute. In the example above, I wrapped the code into an anonymous function. The second is the number of milliseconds it should wait before executing the code. In my example, I set the timer for 5000 milliseconds or 5 seconds. You can tweak this number as desired to achieve what you want it to do. With this code in place in the After Load Code attribute of the form, 5 seconds after the form loads, ‘Hello’ fills in on the progress note field.

Using A Text Template

You can use a text template in myEvolv to make this all a little easier, especially when it comes to formatting your progress note text. Create your default text in the text templates area of myEvolv.

Then within the setTimeout function, before the line of code that sets the progress note html, add the following line of code:

var myTextTemplate = getDataValue('text_template', 'description', '<text template description>', 'template_text');
where <text template description> is the description you have given your text template (beware of special characters). This line of code will grab your text template, then you can just use the variable you just created in the html() method.

Here’s what the final code would look like if you wanted to use your Incident Narrative text template.

Many programs bill for units that are calculated based on duration. For example, programs may bill where 1 unit = 15 minutes of service time. The myEvolv Finance module handles those calculations to generate an accurate claim based on the duration entered in the service documentation but there may be times when you would like the calculated units to display on the form itself. There are no system form fields that do this for you but you can calculate the value with JavaScript and put it into a custom string field for display on the form.

Duration Fields

The first step is to obtain the value in the duration field and we want to do this every time the duration changes on the form so in the On Change code for the duration field, we will use the following code:

var dur = getFormElement('duration');

Duration fields have masked inputs. When you put in ’30’, the myEvolv converts that to 00:30. When you put in ’90’, myEvolv converts it to 01:30. Therefore when you go to retrieve the value in the field, you are given an HH:MM string. The first task in calculating units is to convert this value back to an integer representing the number of minutes.

Split the String

We know the mask for the time is HH:MM so all we need to do is break the string into hours and minutes. We can do this using JavaScript’s split method:

var a = dur.split(':');

Here we have created a new variable that is an array containing hours and minutes. If the initial input was ’02:45′, a is now equal to an array that looks like this:

('2', '45')

Calculate Minutes

Now we have to perform a little math to get the number of minutes.

var mins = (+a[0] * 60 + (+a[1]));

Here, we take the hours in a and multiply that by 60 to get the number of minutes and then add it to the minutes in a. The ‘+’ signs tell JavaScript to cast the values in the array as numerical values so that math can be performed on them. Remember that the value we got from the duration field was a string.

Calculate Units

For the sake of this example, we will use 15 minutes = 1 unit. We simply need to divide mins by the number of minutes that makes 1 unit to get the number of units. However, there is one tricky bit. Often these billing scenarios do not allow for the billing of partial units. That means if the duration is ’00:35′, we want to calculate 2 units, not 2.333333333 units. So in addition to the division, we will also use JavaScript’s Math.floor method so that partial units are rounded down to the nearest whole.

var units = Math.floor(mins / 15);

If you need to calculate a different unit formula, you can do that by changing the number of minutes. For 1 hour = 1 unit, you just make the ’15’ into a ’60’.

Set the Units Value

Finally, we just need to put the calculated units into our units field. I am using a custom string type field.

setFormElement('udf_calculated_units', units);

With this code in place for the On Change event on the duration field, the correct number of units should calculate into the udf_calculated_units field whenever the duration value changes.

I haven’t yet figured out a great way to only toggle the required attribute for a form field so the typical workaround for a conditionally required field to be used on a form is to toggle the form field to be required all of the time but enable or disable the field based on the condition you want. myEvolv ignores disabled fields when it goes to save, even if they are required so you can get most of the functionality you would want in this way. The one scenario you don’t get is if you want the field to remain enable but no longer be required. That’s where being able to have a ‘required rule’ attribute in the form designer would be nice. I am not convinced that there isn’t a way to do this through some clever JavaScript but I haven’t had the opportunity to try anything out yet.

Form Setup

The nice thing about this approach to the problem is that you don’t need to add any additional information to the form itself. A lot of the disable rules that you might learn will involve checking the value of other fields on the form. In this case, we are going to use a form function to check a value in the database behind the scenes.

All you need to do then is setup the field that you want to make required. Be sure to check “Required” for the form field.

Disable Rule

The key to using the Disable Rule attribute in the form designer is that you have to put in a conditional statement that will resolve to true when you want the field to be disabled. It’s somewhat counterintuitive but basically true = disabled and false = enabled.

For this example, we want to figure out if the client is under the age of 18. If the client is under the age of 18, we want to enable the field and require that the clinician enter some data. If the client is over 18, we want to disable the field. So our statement should look something like this:

[[client_age]] > 18

If [[client_age]] is under 18, the statement resolves to false, so the field will be enable. If the client is over 18, the statement resolves to true and the field will be disabled. Now we just need to get the client’s age.

The getDataValue Form Function

One of the JavaScript form functions that myEvolv has included in it is the getDataValue() function. It is used to get a value from a column in the database based on the value of another column in the same table. It takes five arguments, one is an optional conditional statement that we will not get into here. For our purposes, we need to supply it with 4 things:

the table we want to get data from

the column we will match on

the column value we will match on

the column value we want returned

myEvolv has a view called the client_personal_view which contains a calculated column for the client’s age, so the work of calculating an age has been done for us already.

So to get the age of the client we are entering a service for, we call the function like this:

getDataValue('client_personal_view', 'people_id', keyValue, 'age')

Here we are saying, get the value in the age column from the client_personal_view table in the row where the value of people_id column is equal to client_id of our current client. keyValue is a variable that myEvolv creates to hold the client_id when a service event is launched so we can use that in our JavaScript here instead of getting the value from the people_id form field, though that is also a valid option.

This may not be the only or even best way of preventing backdated entries in myEvolv but this method worked for me in a recent configuration.

Scenario

We wanted our prescribers to be able to provide a Script for Therapy Services to children in our preschool services program from myEvolv. Scripts for Service must have a start date on them and that start date needs to be no earlier than the date indicated on the child’s IEP but cannot but previous to the date that the script is being signed.

Further, an administrative assistant was going to be setting up the scripts in myEvolv and then the prescribers were going to be reviewing and e-signing them. We could imagine a scenario where the administrative assistant put a date, for example (9/1) on the script, believing that the prescriber would e-sign it on or before that date but the prescriber does not get into myEvolv to sign it until after that date has passed and then the script gets e-signed as though it were backdated. We needed a way to prevent the start date from ever being previous to the approved date while also allowing the start date to be in the future.

Form Design

The actual_date field was not suitable for use as the script start date since we needed to be able have multiple scripts that start on the same day for an individual. If I set the actual date as ‘Date Only’ Display Type Code, then two scripts in the same day would overlap at 00:00 AM. In this case I ended up creating a new database field for my Start Date and kept actual date on the form, receiving todaysDate() as the default value. This more or less prevents the service overlap problem. My new database field is named udf_rx_4_svc_start and is Date Only.

The end date on the script is using the expiration_date column and is also using the Display Type Code “Date Only”.

Before Save Code

The first task to accomplish is to prevent a user from saving the form with a backdate on it. For this I used the Before Save code property on the form. This code executes every time that the form is saved BUT because of the algorithm myEvolv uses to save form data, the udf_rx_4_svc_start column in the database will only be updated if the form field has been flagged as being modified. This is something that I was not able to figure out how to do in the Before Save code yet and is largely responsible for what feels like a more-complex-than-is-strictly-necessary-solution — more on that later.

First step is to get the value that is on the form field and turn it into a JavaScript date object.var start = new Date(getFormElement('udf_rx_4_svc_start'));

Second step is to get today’s date and turn it into a JavaScript date object. todaysDate() is a myEvolv form function that you can use to get today’s date in a format suitable for placing in a myEvolv form field.var today = new Date (todaysDate());

With that accomplished, we can compare the two date objects to see if the date on the form is previous to today’s date and if so, set the form field’s value to today’s date.if(start <= today){{setFormElement('udf_rx_4_svc_start', todaysDate())}};

Note that the { and } brackets are doubled up in the conditional statement. This will prevent the “Not a Valid XSLT or XPath Function” error previously discussed here.

With this code in place, when a new Script for Service is entered or a draft Script for Service has it’s udf_rx_4_svc_start field modified, myEvolv will check to make sure that the start date is not not in the past and if it is, update the start date to today’s date. If the date is today’s date or a future date, it is left as it is.

Full Code Block

On Load Script

Just the Before Save Code alone would not be enough to prevent backdating. We still have the possibility of someone simply opening the draft and e-signing the form as in our scenario where the prescriber gets into myEvolv to e-sign scripts later than intended. Even if the form is edited in some way, if the Start Date is not touched, the Before Save code will execute but the column will not be flagged as modified and myEvolv will ignore it when updating the database. My approach here was to try to update the form as it loads upon viewing or editing so that myEvolv would see the column as modified when saving. I was unable to get the toolbar containing the ‘Save’ button to recongize the change, however, I was able to still get the desired effect another way.

The first thing to keep in mind with the On Load Script is that the form DOM has not loaded yet when this code runs. You can not therefore target the form field with JavaScript, update its value and focus/blur to make myEvolv notice a change to the value as we can with the On Click and On Change Scripts. Instead, you have to manipulate the Record XML Data before it gets loaded into the form.

The first step here is to determine whether the script had been signed. If it has been signed, it will have a non-null date_locked value. We check for this by using the myEvolv form function getDataValue() and then seeing if the form is being opened for viewing or editing.

This code gets the value of date_locked from the event_log table where the event_log_id is equal to keyValue which is a variable equal to the event log id of the current event you are looking at.

Then the code checks to see if there is a locked_date. If the locked date is blank AND the form is opened for editing, then it will execute the rest of the code. So basically, only perform a date manipulation if we are still working with a draft. If you leave this piece out then every time you look at a completed script for service in the future, myEvolv will overwrite the form field value for start date to be today’s date and you will be scratching your head.

Inside the ellipses we start the date manipulation. First we load the node for udf_rx_4_svc_start from the XML Record so that we can manipulate it.node = formXML.documentElement.selectNodes("form_group/form_item [@column_name = 'udf_rx_4_svc_start']");node = node[0];
This code returns an Array of all of the nodes in the XML documents with the column_name “udf_rx_svc_start”. There is only one but it is in an array so we load it into our variable directly on the next line.

Then we get the start date value and turn it into a JavaScript date object.var start = new Date(node.text);

Then we do the same for today’s date.var today = new Date(todaysDate());

Now we check to see if start date is before today’s date and if so, we will update the text of the node to be today’s date.

I also set the “modified” attribute to ‘true’ for this node. I don’t know if that makes a difference in this setup but I am including it since that is how my code is and it works.

If you leave the code as it is like this, when the form loads, if the start date is previous to today’s date, the value on the form will have been updated to today’s date AND the form field will be maroon like it is when a form field is changed. However, you will also notice that the “Save” button is nevertheless disabled and a user would be able to e-sign the service without being forced to hit save. And apparently, even though a “saving…” dialog pops up upon e-signing, the form is not saved. I tried a bunch of things to try to get the save button to enable and the e-sign button to disable but it is difficult since the form DOM is not loaded at the time that the On Load script runs. In the end, I decided to just call the save form function directly.

So where the ellipses above are, I putSaveForm2();

The end result here is that when the form is opened for editing, if the start date is before today’s date, myEvolv will update the start date to be today’s date and then save. The users will see the form start to open and then abruptly close if the conditions are met. When they reopen it, they will find that today’s date has been updated to today’s date and they are free to e-sign.
